It's been almost two years since I started Aikido and this website has been a great source of advice and wisdom for me. It provides great help to the new Aikidoka.
It has occurred to me that it might be nice to have a list of the best advice for the "Newbie." Short and to the point advice that will help them on their way. If you want to explain a little more in detail make a note below the main point of advice. I'll start it off with this piece of advice:

1. Show up to class on a regular basis.
(Regular attendance is crucial to learning and skipping your scheduled workouts can get to be a habit and hinder your growth. Try to be early to stretch and warmup and be open to staying a few minutes after class to cleanup and maybe pick up some pointers)
